Background: The benefits of breastfeeding for mothers and infants are well known. However, in Taiwan, the average breastfeeding rate remains below the World Health Organization recommendations. Breastfeeding self-efficacy is a known predictor of breastfeeding.

Research aims: To determine: (1) the relationship of sociodemographic factors to prenatal breastfeeding self-efficacy, and (2) the relationship of sociodemographic factors and prenatal breastfeeding self-efficacy to breastfeeding behavior at 8 weeks postpartum among women living in Taiwan.

Methods: This was a prospective cohort study of 206 pregnant women collected in an outpatient clinic located in Taiwan. The validated Chinese version of the Prenatal Breastfeeding Self-Efficacy Scale (PBSES) was used to measure self-efficacy for breastfeeding during pregnancy. At 8 weeks postpartum, participants were contacted by telephone to obtain information regarding infant feeding method and duration.

Results: The mean age of the pregnant women was 32 years, and the mean prenatal breastfeeding self-efficacy score was 78.6 (SD = 10.6). Scores differed across levels of maternal education, previous breastfeeding experience, and support systems. Prenatal breastfeeding self-efficacy scores were highest among participants reporting spouse support versus other types of support. Maternal age and prenatal breastfeeding self-efficacy were predictive of breastfeeding duration. A 1-year increase in maternal age was associated with a 6% lower likelihood of breastfeeding for at least 2 months postpartum, and a 1-point increase in the prenatal breastfeeding self-efficacy score was associated with a 14% increase in the likelihood of breastfeeding for at least 2 months postpartum.

Conclusions: Prenatal breastfeeding self-efficacy may help predict breastfeeding continuation among Taiwanese women in the first 2 months postpartum.

Background: Birthmark Doula Collective, a cooperative that provides doula and lactation services in the Greater New Orleans area, mounted an emergency response after two Category 4 storms: Hurricane Laura (2020) and Hurricane Ida (2021). The response included activating a no-cost emergency perinatal and infant feeding hotline. Both disasters coincided with a resurgence of COVID-19 infections in Louisiana.

Research aim: The aim of this study is to understand how an emergency perinatal and infant feeding hotline supported infant and young child feeding in emergencies during hurricanes in Louisiana.

Method: This study used a cross-sectional, retrospective qualitative design in a population with low breastfeeding rates. We conducted a content analysis of 97 hotline call logs from Hurricanes Laura and Ida, focus groups with lactation support providers who staffed the hotline during either storm (n = 5), and interviews with mothers who called during Hurricane Ida (n = 2). Focus groups and interviews lasted 30 and 60 minutes, respectively. Transcripts were analyzed using thematic analysis techniques.

Results: Call logs revealed infant feeding needs (e.g., mastitis, low milk supply, relactation, and infant formula requests) and non-infant feeding needs (e.g., infant supplies, perinatal and infant care referrals, shelter information). Infant formula was the most requested supply during both hurricanes. Maternal participants discussed family vulnerabilities during Hurricane Ida. Staff described training and strategies to provide support while maintaining their own well-being.

Conclusion: Providing a free emergency hotline service is one way to support pregnant and postpartum people and their families seeking infant feeding advice, supplies, and support in the immediate aftermath of a disaster.

Professor Fiona Dykes is Professor Emerita of Maternal and Infant Health at the University of Central Lancashire in the United Kingdom (UCLAN). Fiona has a particular interest in the global, sociocultural, and political influences upon infant and young child feeding practices; her methodological expertise is in ethnography and other qualitative research methods. She founded the Maternal and Infant Nutrition and Nurture Unit (MAINN) in 2000 which she led until she retired from her full-time professorship in 2020. Fiona established the associated MAINN Conference in 2007. The MAINN conference is a 3 day, international, peer reviewed event held bi-annually in the United Kingdom and, more recently, in alternate years overseas (Sydney, Australia; Falun, Dalarna, Sweden; and Florida, United States). The conference draws together key researchers in the field of infant and young child feeding from around the world. Fiona was a founding member of the journal Maternal and Child Nutrition. She is author of Breastfeeding in Hospital: Mothers, Midwives and the Production Line (Routledge) and co-author, with Dr Tanya Cassidy, of Banking on Milk: An Ethnography of Donor Human Milk Relations (Routledge). She is also joint editor of several books including Infant and Young Child Feeding: Challenges to Implementing a Global Strategy (Wiley-Blackwell) and Ethnographic Research in Maternal and Child Health (Routledge). This interview was conducted on April 20, 2023, by Dr. Tanya Cassidy, and is based on a verbatim transcription and edited for readability.TC = Tanya Cassidy; FD = Fiona Dykes.

Background: Donor human milk is recommended when infants are unable to be fed their mother's own milk or require supplementation. For-profit companies use technologies to create human milk products for infants in the neonatal intensive care setting without consistent guidelines and regulatory frameworks in place. This commercialization of human milk is inadequately conceptualized and ill-defined.

Research aims: The aim of this study is to conceptualize and define the commercialization of human milk and discuss the need for policy guidelines and regulations.

Method: Using a concept analysis framework, we reviewed the literature on the commercialization of human milk, analyzed the antecedents and potential consequences of the industry, and developed a conceptual definition. The literature review resulted in 13 relevant articles.

Results: There has been a surge in the development and availability of human milk products for vulnerable infants developed by for-profit companies. Commercialized human milk can be defined as the packaging and sale of human milk and human milk components for financial gain. Factors contributing to the commercialization of human milk include an increased demand for human milk, and consequences include potential undermining of breastfeeding. The lack of guidelines and regulations raises concerns of equity, ethics, and safety.

Conclusion: The industry is rapidly growing, resulting in an urgent need for consistent guidelines and regulatory frameworks. If left unaddressed, there could be potential risks for donor milk banking, the future of breastfeeding, and infant and maternal health.

The World Health Organization recommends assessing compliance with key clinical practices of the Baby-Friendly Hospital Initiative (BFHI; Steps 3-9) using birthing women's self-reports. Globally, compliance is mainly assessed using health staff reports, and the use of women's self-reports in selected countries has deviated from the Global Standards for the BFHI. Therefore, we aimed to provide insight into the appropriate method of incorporating women's self-reports in assessing compliance with Steps 3-9 of the BFHI. We developed questions and coding algorithms for assessing compliance with Steps 3-9 based on Global Standards for BFHI compliance, and implemented them via a cross-sectional survey of 302 women who gave birth to a live baby in Sri Lankan hospitals. Compliance with specific practices within each of Steps 3-9 and overall compliance with each step were described as percentages. Compliance with specific practices and each BFHI Step ranged from 15.9%-100% and 7.0%-100%, respectively. Our findings particularly emphasize the potentially enhanced usefulness and robustness of assessing all specific practices within BFHI key clinical steps and not focusing only on one practice within a step, to derive more useful health service guidance globally for capturing BFHI compliance and its impact on breastfeeding outcomes. This method could be translated across multiple settings globally. It would enable more specific identification of care advancements required by health services to improve the effectiveness of breastfeeding support and address the prevailing undervaluing and under-use of women's experiential data to evaluate and guide health service improvement.

We discuss the evolution and composition of breast milk and briefly describe how mammalian evolution resulted in lactation, which played a crucial role in infant growth and development. We focus on three teleological factors that significantly contribute to breast milk composition: (1) biological sex at birth, (2) gestational age, and (3) circadian rhythms. We also explain how these factors lead to variability in human milk composition. We emphasize the importance of standardizing the definitions of "preterm" and "term" to accurately study the effects of gestational age on milk composition. Finally, we discuss the role of the circadian clock in regulating lactation and the impact of breast milk on fetal and infant sleep. Investigators may integrate these critical factors when designing a research study that involves the collection of breast milk samples. Teleological factors greatly influence milk composition, and these factors may be considered when designing a study that requires breast milk. We provide both the rationale and application of solutions to address these factors.
